cons: expensive, data not interchangeable between the 5 and 6 version.
Big cons ... you have to manually insert all the version 5 data into 6 ... big pain in the ars!
Not very fair but brilliant marketing strategy.
New joiners have to buy 6 but old customer are really not happy ... read the forum inside Corodine webpage ... and what will happen with the version 7?
Good strategy to collect money now but absolutely poor strategy on the long run because pilots don't want to spend 75$ a year for a logbook ... sorry ... Corodine have a great product but they are loosing customers!
